## Homework Statement

## Homework Equations

R2=R1(1+alpha(t2-t1))

## The Attempt at a Solution

R1=250/5=50ohms

R2=250/3.91=63.94ohms

R2=R1(1+alpha15degrees(t2-t1))

63.94=50(1+1/254.5(t2-15))

t2=

Now I found this online but the answers provided still don't match, 84.25 being the closest.

When I manipulate the equation I get a totally different answer:

63.94=50(1+1/254.5(t2-15))

63.94/50=(1+1/254.5(t2-15))

1.2788/1+1/254.5=t2-15

1.274=t2-15

t2=1.274+15=16.274 degrees

Please help me understand where I am going wrong.
